As we've said before, factory versus tuning isn't exactly a fair game. But since we'll always be curious when it comes to performance, we're bringing you this highly competitive drag race between a 661 HP Ferrari FF and a 700 PS MTM Audi RS6 - courtesy of GTboard.

At the Essen Motor Show, which is Europe's version of the SEMA aftermarket and tuning event, VW Group specialist ABT will introduce three cars, including a world premiere "based on a sporty Coupe" from Audi.

The hideous car in the photo is a mash-up of the UK’s least reliable cars according to automotive specialist Warranty Direct. Dubbed “Horrific 40RR0R”, it’s the UK’s nightmare car, as it costs an average £550 when it breaks down every other month.

Audi has applied a subtle facelift to its A6 family, which includes the A6 sedan and wagon, A6 Allroad, S6 sedan and wagon and RS6 wagon. All models receive updated headlights and taillights, as well as revised engines, with the facelift being very similar to the one of the A7 Sportback.

As you have heard, Audi owns Ducati, so the folks from Auto Express thought that is a good enough reason to stage a track battle between the most powerful products from each brand – the Audi RS6 and the Ducati 1199 Panigale R.

Audi UK has revealed images and information on the forthcoming RS6 Avant Plus. We previously reported on (Head of quattro GmbH) Stephan Reil’s confirmation of the model, and published potential spy shots.

Apparently, there are many European and in particular, German owners of the Audi RS6 Avant who aren't content with the twin-turbocharged 4.0-liter V8's 552-horses (560PS) and 516 lb-ft (700 Nm) of peak torque that secure a 0-100km/h (62mph) time of 3.9 seconds.

The C7 generation of the Audi A6 series has been around since November of 2010, meaning that a facelift is on the horizon for the regular models, and possibly for the RS6 Avant as well, even if it was introduced just last year.

The already ludicrous Audi RS6 Avant has just become even more insane, courtesy of a tune from ABT Sportsline that takes the standard model's 4.0-liter turbocharged V8 from 552hp (560PS) and 516 lb-ft (700 Nm) to a stratospheric 720hp (730PS) and 920Nm (678 lb-ft) of peak torque for a top speed of 320km/h (199 mph).

If you want your new 2013 Audi RS6 Avant to perfrom better than it already does (not that you’d need to, really), and have subtle visual tweaks to hint at it, then VW Group tuner ABT Sportsline is one of the best bets. Crazy-powerful Audis are their most extreme products, and this new RS6, with its 700 PS (690 hp) tuned twin-turbo V8 is close to the top of the pile.

As if the stock Audi RS6 Avant wasn't crazy enough to make even a mundane trip to the supermarket a racing affair, O.CT Tuning has unleashed a performance program to turn Ingolstadt's fastest station wagon into a wilder supercar killer.
